如何在rails 4中渲染部分来自.js.erb的文件？

In my rails application I have dragdrop.js.erb in /assets/javascript folder. In which I have an ajax block which should render a partial in a div with an on click action. I tried many things but I can't get it working. Any help would be appreciated.

在我的rails应用程序中，我在/ assets / javascript文件夹中有dragdrop.js.erb。其中我有一个ajax块，它应该在div中使用on click动作呈现部分。我尝试过很多东西，但是我无法让它发挥作用。任何帮助，将不胜感激。

Here is the code:

这是代码：

 $.ajax({  
   type: "GET",    
   url: "<%=  Rails.application.routes.url_helpers.cookbooks_path %>",
   success: function(resp){
  $("#property").load("<%= escape_javascript (render :partial => 'recipes/package_form') %>") 
   }

Asset Pipeline

资产管道

Firstly, you need to make sure that you don't use any Rails dynamic path helpers in your javascript directly.

首先，您需要确保不直接在javascript中使用任何Rails动态路径助手。

The issue is that if you pre-compile your asset pipeline, you'll typically find these dynamic path helpers won't work correctly. Although there's nothing "wrong" with it - I tend to keep Rails back-end code completely separate from the front-end, as to ensure the versatility of the application:

问题是，如果您预编译资产管道，您通常会发现这些动态路径帮助程序无法正常工作。尽管它没有“错误” - 我倾向于将Rails后端代码与前端完全分开，以确保应用程序的多功能性：

#app/assets/javascripts/application.js
$(document).on("click", ".element", function(){
   $.ajax({  
     type: "GET",    
     url: "/cookbooks"
  });
});

This will send a "naked" Ajax request (no params / body) to your controller backend:

这将向您的控制器后端发送“裸”Ajax请求（没有参数/正文）：

#app/controllers/cookbooks_controller.rb
Class CookbooksController < ApplicationController
   def index
      @cookbooks = Cookbook.all
      respond_to do |format|
        format.html
        format.js #-> loads /views/cookbooks/index.js.erb
      end
   end
end

The trick here is that you can now populate your index.js.erb file with the params necessary to render the partial:

这里的技巧是你现在可以使用渲染部分所需的参数来填充index.js.erb文件：

#app/views/cookbooks/index.js.erb
$("#property").html("<%=j render :partial => 'recipes/package_form' %>")

This should work for you

这应该适合你

Your problem is that you are trying to use render in assets, however, render is not available in assets

您的问题是您尝试在资产中使用渲染，但渲染在资源中不可用

You should move your .js.erb file to an appropriate directory under app/views

您应该将.js.erb文件移动到app / views下的相应目录中
